Maruti Suzuki — Engine rpm problem

Address:

Gurgaon, Haryana

Sir, I had purchased a Maruti Swift VXI engine No. K12MN1262673 and chasis NO. MA3EHKD1S00457626 ON 12 JUN 2013 FROM APRA AUTO GURGAON. after 3 months it was noticed that after starting engine rpm goes to 1200 and settles down to 1000 rpm after one minute that is ok but after running few kilometer it drops to 550-600 rpm which was not there initially. This causes the vehicle to cut off at some times specially driving through the long traffic jam situation. I had reported to this to service agent apra but they say it is ok. I had complaint the same in every servicing but no result yielded. Pl. guide me what to do. It appears that they are waiting to finish the warranty period go the car than only they will ask me to pay money for the fault. Pl. guide me what to do if the behavior of the vehicle is as per the standards of the company or otherwise instruct to service agent accordingly. I have no trust with the apra service agency it appears they do not analyst it properly. My registration number HR 26 BZ 8169 Contact No, [protected] & e mail [protected]@ gmail.com. I had been pursuing the case since first week jun 15 with no response from maruti company side. What should I do? kindly take up the matter with company.
